What is potential energy
100
This is done only when force causes a change in the position or the motion of an object IN THE DIRECTION OF THE APPLIED FORCE.
What is work?
100
This is energy of motion.
What is kinetic energy?
100
This is what the law of conservation of energy says.
What is energy cannot be created nor destroyed?
100
This is the label for mass.
What is grams or kg?
200
The parts of the equation PE = mgh that weight tells you.
What is mass x gravity
200
This is the equation for calculating work.
What is force x distance?
200
These two things influence kinetic energy.
What is mass and velocity?
200
This is why a ball never bounces as high on the second bounce as it does on the first.
What is energy is lost as friction?
200
This is the label for distance.
What is meters?

9.8 m/s^2
What is the force of gravity.
300
If you are carrying a bowling ball from the front of the room to the back of the room, have you done work (if you haven't lifted it or put it down)?
What is no?
300
This is the equation for kinetic energy.
What is KE = 1/2mv^2.
300
The is the measure of how much useful work a machine can do.
